YNU weekend in Upper Teesdale 1-2 Aug 2026 -Day 2

 What did we find on day 2 of the Yorkshire Naturalists Union weekend visit to UpperTeesdale on 1-2 August 2026?

I joined several people in the YNU at the village of Holwick near Middleton-in-Teesdale as part of the Teesdale weekend. You might be able to see one or two people in this picture disappearing into the distance.   NY903270

The day started sunny - remember this is the year of the drought - but fortunately Teesdale still had some greenness left in the vegetation.

Terry in the seat had just given us maps. He suggested a walk following this road which turned into a track for about a mile or two (past Holwick Scar on the left ) then taking a footpath down through a field and a very steep slope with scrub to a wet meadow/flush at the bottom then returning along a track. The walk turned out to be only 2.5 miles but seemed much longer as we kept stopping.

First we had a look at the wall nearby (off ) on the left.

Jill showed us some Umbilicaria cylindrica  (Fringed Rock Tripe lichen) In VC 65, indeed in all Yorkshire there are only a few records of this species, nearly all in Upper Teesdale. Its main locations are  in the Lake District and Scotland and Wales

She had been shown this on a recent visit with some BLS Members from the NE of England.

A close up of this Umbilicaria cylindrica show its black gyrose apothecia and some branched black cilia at the thallus lobe margins. 

The walls include rock from the Whin Sill which is dolerite - It has  quartz and  minerals in it. I think this rock is fairly acid.  (Certainly acid, compared to limestone)

On a cap-stone nearly by was some Polycauliona (formerly Xanthoria) candelaria sens lat. (Shrubby Sunburst Lichen). This tends to grow where birds perch leaving nitrogenous droppings. This is more abundant in eastern Britain.

We set off up the path - Stella and Ian, Jill, Janet and myself.  with the tall cliffs of Holwick Scar on the left. (The Whin Sill) . Near the summit of the path a big boulder with white lichens cried out to be looked at. 

It had the lichen Ophioparma ventosa (Alpine Bloodspot lichen) growing on it

Ophioparma ventosa has red apothecia. It has areoles (islands)  which have a lumpy warted surface.

Parsley Fern, common in the Lake District was growing by some rocks.

We came to a stile supported by two sheep (Read about the sculptor here)

It  - the stile  to take the footpath down -  was only a mile from our starting point, but seemed much further in the dry treeless exposed landscape

The field was grazed and relatively flat at first. We found a moth - the Barred Straw Gandaritis pyraliata. The forewings cover the hindwings.

The path then got much steeper.. The slope was fenced off from grazing so the Juniper scrub was able to grow and the vegetation was longer. Parts were wet heath. I would have liked to stop and explore but the path between the shrubs was  very narrow and steep , and no space for us to stop and sit. So we continued down to a flatter pasture with flushes at the bottom, found a tree to shelter from the sun on a rabbit grazed slope and had lunch.

I enjoyed my fish bites and a few chips, saved from supper yesterday at Middleton-in-Teesdale Fish and Chip shop. Doubly delicious when you are hungry.

In the flush some rushes had galls. Larvae from the insect Livia junci (formerly juncorum) cause the this

Here are some lichens  from a boulder in the stream in that paasture/meadow, and from rocks and the gate nearby.. But I am not confident of their names

A Cladonia on rock protruding from the flush.

Hypogymnia tubulosa on the gate post

Possibly Ochrolechia androgyna   - but I did not test it with chemicals.

I went out of the field round to the land above the pasture - the fenced off area  called The Bands on the map that we had walked down through. Here the Juniper was growing on wet heath - but with flush species too including Tawny Sedge  - so it looked a nice mix. There was Sundew in the sphagnum, and Pyrenean Scurvey-grass I wondered if there were special species of Sphagnum but there was not time to look.

Below is a picture of the "Black caterpillar" - an beetle larva mentioned in the video above.

Further on we came to a new plantation. I wish they did not plant the trees so closely.

This Rowan at the edge had was found to have various things on its leaves including the Rust fungus which needs Juniper as its alternate host.  See the video below

Galls caused by a midge larva

Xanthoria calcicola  (This does not appear to have an iNaturalist name)

Xanthoria calcicola. This has a warty lumpy thallus.

I still may add a couple of videos.   Special thanks to Jill with her knowledge of galls and insects.

I had an interesting trip back through VCs 65,69,65 again and 64 - maybe one day I will do a post on that.

I am looking forward to the 2026 YNU AGM on 7 November at York and seeing friends  there again.

YNU weekend in Upper Teesdale 1-2 Aug 2026 -Day 1

Day1 -Yorkshire Day (1 Aug) was a walk beside and above High Force on the "Old Yorkshire" side of the River Tees  - VC 65. The north side is  County Durham  (VC 66)  

The previous evening I had returned from the British Lichen Society ~Meeting in Worcestershire. - to Settle.

Both Settle and Middleton-in-Teesdale are near the watershed of the Pennine ridge. I set off on my journey north from Settle, up the Ribble to Ribblehead, then following the tops of the Pennines via Hawes  then up the Ure (which flows wast) up over the tops to the top of the Eden Valley the Eden-  flows west.

The picture below has Wild Boar Fell on the left, Mallerstang on the right and the valley leads down to Kirkby Stephen with Brough beyond. Brough is at the foot of the pale hills you see in the distance topped by white clouds.  This photo was taken at 9.23am and I was supposed to be at High Force, Middleton-in-Teesdale, 18 miles over the tops beyond Brough by before 10.30..

I met the part of the group that had not yet set off.

I followed them at my own pace,  sampling the raspberries on the way.

There was a view point of High Force - only one side had water today.

It is worth enlaging this picture (maybe press (control +) to read about the geoplogy

The group had continued to the section above the waterfall, and were having lunch

There were excellent flush communities to explore. I just show a picture of the rare Variegated Horsetail  Equisetum variegatum here.  It  does grow in a few flushes round Settle too (well Malham) - but it is good to have a picture to fix points about it:- the stems creep; the black scales round the stem have long white points. and there are papillae on the stem.

I spent much of the time with Ian and Stella,  making a list of sedges.  All too soon it was time to return..

Across the Wynch Bridge

In Middleton we had the customary plenary tea and reporting session.

We then had fish and chips on a bench outside the local fish and chip shop in Middleton in Teesdale.- I had fish bits-  A small piece of fish cut up and the bits fried separately - They were EXCELLENT - And I saved half which I ate for lunch the following day.

People returned home. I was lucky to find space and treat myself to stay at in the Langdon Beck Hotel, with Ian and Stella.

After the meal Ian took us up for a drive to Cow Green Reservoir.

We watched sunset over Dunn Fell and Cross Fell. Just four month's earlier I had been on the top of Great Dunn Fell and Little Dunn Fell, looking down to Cow Green with the British Lichen Society. 

Here is a picture taken then, on 13 April 2026 at 11.07am with the Lichen Society 

   

~However on 1Aug 2026  it was getting darker

So we returned, stopping to look at owls on the way.

I slept well.

I got up at 6am for a walk - to see more of the Hotel at Langdon Beck.. 

but that is for tomorrow...
